Changed the fluid in the transmission for the first time. The fill plug was so tight it came out with aluminum from the housing. It appears it was over torqued from the factory, as the o ring was pinched into and beyond recognition. I thought replacing the o ring and mildly tightening it would seal, but not so good. I need to helicoil it. Anyone know the thread specs? It looks like a M14 2.0.
